Original logs + fresh replication · Experiments 1–6

Full Codex trajectories

Choose a conversation to read every prompt, recorded reply, reasoning summary and permitted harness call. Original and fresh runs are kept separate.

Built-in Codex tools: off. All 244 fresh turns passed the event check with zero built-in tool calls. Experiments 3 and 6 permit a separate experiment harness; its calls are explicitly labelled. Experiments 1, 2, 4 and 5 contain no execution calls.
